Netify DPI - netifyd Agent
If we're doing our jobs right, people won't notice the network: the important Zoom business call will always work, the ping time to the Fortnite server will never hiccup, and the streaming movie won't pixelate or (gasp!) pause. But the expanding role of applications in our daily lives and the pervasiveness of network-ready devices have increased our dependence on the network.
The days of cut-price and unpredictable networks are coming to an end. Today's network has to be smarter.
- Quality of experience (QoE)
- Digital experience monitoring
- Application-based network policies
- Next-generation security and firewall protection
Though the above list includes a few buzzwords, we certainly understand that these types of features make the network experience better. Here are just a few examples:
- Prioritizing network traffic based on application and modern protocols, not IP lists
- Pinpointing bottlenecks by application, e.g. Microsoft Teams response times
- Identifying malicious traffic, even when encrypted
- Creating application-level QoS/latency policies
- Generating latency-friendly routing policies in multiWAN/SD-WAN environments
How It Works
The open source Netify DPI Agent - netifyd - does one thing and one thing very well: network analysis using deep packet inspection (DPI). The DPI Agent passively captures network traffic and then produces network metadata and policies:
- Network Policies
- Data Streams
- Detection Metadata
- Stats and Performance Data
- Status Data
Netify agent highlights include:
- DPI metadata extraction
- Protocol detection
- Application detection
- Layer 3 network hooks
- Bandwidth information
- Network policy integration
- Data streams
- Open source
- Small footprint
- Custom signatures
- Optional cloud intelligence
Why Netify DPI?
- To Focus on your core product
- A lower total cost of ownership
- Reliability and experience
- Knowledge and support
- Open source, open integration
- Signature updates
The protocol detection is handled by a modified version of the nDPI library. Netify adds handling for run-time application definitions, network policies, JSON data streams, packet dynamics, packet pipelines, and more. The source code is ready to use on various popular Linux distributions, FreeBSD, OpenWRT, Raspberry Pi and more. If you're a technical guy, you can find all the source code on Netify's GitLab project page.
